Highway design is the process of understanding, designing and developing roads and their supporting infrastructure, from the road surface and earthwork to curve radius and beyond.

Drainage strategies are now an essential requirement during planning no matter the size of the development. A Surface Water Drainage Strategy (also known as a SuDS report) provides a natural approach to managing surface water run-off from a site by reducing the rate of run off through the promotion of infiltration or by storage.
